  1. They have fixed a bug, is my guess. Concatenating by using null char is a huge security smell. Multiple file types are [supposed to be] defined by using the semicolon separator. Does "*csv;*txt" not work?
  2. It's probably DICOM which is partially supported in the Biomedical Toolkit.
  3. The variant attribute cannot have duplicates. If you set it, it overwrites the previous values. With the "array with tag" you can have duplicates.
  4. Try print(json.dumps(convert['test'], ensure_ascii=False))
  5. Yes. that's exactly what I am thinking (but poorly communicated). This is a common known gotcha for VI's with shift register memories (not the first call primitive per say). It will probably only bite you when you have multiple instances and where it's being used with different CRC types with different integer lengths. Here's an example: sub VI set to Preallocated (what we expect-11 more than the intialise value) sub VI set to Shared: If you run continuously, you will see other values as different threads become available at different times. rentrant clones.zip
  6. Nice. This is probably one of the only times (1 in 1,000,000) I would suggest an xnode may be preferable-and specifically for the lookup tables which should always be more performant. With an xnode, one can pre-calculate the tables at design time based on the type and save the cost of generating the table at first run run. This will also mean that the calculation will be constant time whether first called or later. xnodes are tricky and complicated beasts so I could understand not wanting to go down this hairy rabbit hole littered with rusty nails. Speaking of the table generation; I noticed you have the VI set to reentrant clones. I think this will be a problem when you run multiple instances as the shift registers may not contain the values you expect per instance.
  7. My takeaway from the roadmap is that they are concentrating on interoperability and relegating products to backend services. This was the direction NI were taking before Emerson but expect it's taken on a new impetus since the takeover. I expect the awful gRPC to be leading the charge so they can plug the NI products to their products. Unicode support isn't a consideration for that since the UI will be elsewhere.
  8. The ini (or config file as NI calls them) are only written when the reference is closed. You could put the flush in there but I don't think that's your problem. I have seen this before and it is usually on a failing hard drive or one that is about to fail. NTFS has a sort of self healing which is insidious for small files (less than the cluster size) and this is the usual result of it "healing". Larger corruptions are more detectable with chkdsk. (source) I would take a look at the S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) information of your disk and pay particular attention to the write failures/errors.
  9. ..and splitters. It's these sorts of issues that are the reason some of us abandoned the LabVIEW UI altogether.
  10. There is an "Element" property for arrays. You can get that then cast it to the element type. Then your other methods should work (recursion). Boolean Get Image Testing_sr.vi
  11. To be fair. Those that VDB suggested aren't really protocols, they are middleware. One is based on OPC, the other is a translation service into an API. SILA is interesting in that it's basically what CoAPs does so I think your cartoon would definitely apply there Personally. I think they should just make all devices SCPI compliant and be done with it
  12. Test Stand is a test sequencer so what you have now isn't even in the same paradigm. In terms of LabVIEW, you have some limited block functionality that could be compared to Express VI's (which we don't use). From what I can tell, It seems to be the Python version of Node Red (Javascript). It has a place but people are very quickly going to be dropped into text coding for anything more than hobbyist applications. Many people on this forum (not me) are also adept Python Developers already and I expect they will weigh in sooner or later. If you are going to target the LabVIEW community, I would suggest you work on your videos. From what I can tell, they are pretty much: Plug in some wires Magic happens Trust me bro, the pretty pictures are because of the magic".
